BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a net knitting method and, moreparticularly, to a net knitting method.

2. Description of the Related Art

With reference to FIGS. 1-3, a conventional method for knitting wovenobjects is carried out on a weaving machine disclosed in Taiwan PatentPublication No. 252370 entitled “IMPROVED METAL GABION SPECIAL MACHINE”and Taiwan Patent Publication No. 291714 entitled “IMPROVED GABIONWEAVING MACHINE”. The weaving machine mainly includes a weaving unit 1.The weaving unit 1 includes a base assembly 11, a plurality of weavingholes 12, a plurality of rotating assemblies 13, and a driving member14. The base assembly 11 is comprised of a first base 11′ and a secondbase 11″. The first base 11′ has a first abutment face 111′ abutting asecond abutment face 111″ of the second base 11″. Each weaving hole 12is comprised of a first half hole 12′ and a second half hole 12″. Thefirst half holes 12′ are formed in the first abutment face 111′ of thefirst base 11′. The second half holes 12″ are formed in the secondabutment face 111″ of the second base 11″. Each first half hole 12′ (12a′, 12 b′, 12 c′) is aligned with one of the second half holes 12″ (12a″, 12 b″, 12 c″) to form a weaving hole 12. Each rotating assembly 13is rotatably received in one of the weaving holes 12 and includes twowire holes 131. Each rotating assembly 13 is comprised of a firstrotating member 13′ (13 a′, 13 b′, 13 c′) and a second rotating member13″ (13 a″, 13 b″, 13 c″). Each first rotating member 13′ has a firstwire hole 131′, and each second rotating member 13″ has a second wirehole 131″. Wires 3, 3 a, 3 b thread through the first and second wireholes 131′ and 131″. The driving member 14 is used to drive the rotatingassemblies 13 to rotate. As an example, each rotating assembly 13 hasteeth on an outer periphery thereof, and the driving member 14 has atoothed section to drive the rotating assemblies 13 to rotate.

The weaving machine preferably includes a coiling unit 2 on a side ofthe weaving unit 1. The coiling unit 2 is driven by a power unit to coila net formed after weaving.

With reference to FIGS. 2 and 3, the conventional method for knitting anet includes threading a wire 3 through each wire hole 131, with an endof the wire 3 extending through the wire hole 131 and then extendingtoward the coiling unit 2. The wires 3 are continuously coiled andpulled by the coiling unit 2. The subsequent steps will be described inconnection with the first rotating member 13 a′, 13 b′, 13 c′ and thesecond rotating member 13 a″, 13 b″, 13 c″ in FIG. 3.

With reference to FIGS. 3-5, the driving member 14 is then used to drivethe rotating assemblies 13 to rotate a plurality of full-cycle turns,such as two turns or three turns, such that the first rotating member 13a′, 13 b′, 13 c′ and the second rotating member 13 a″, 13 b″, 13 c″ arestill respectively located in the first half hole 12′ and the secondhole 12″ after full-cycle rotation. By continuous coiling and pulling bythe coiling unit 2, a first row of twine portions 3 w is obtained, asshown in FIG. 4.

With reference to FIGS. 5-7, the first base 11′ and the second base 11″are then moved relative to the first abutment face 111′ and the secondabutment face 111″, respectively. In an example shown in FIG. 1, thefirst base 11′ is moved rightward (first direction) to a position inwhich each first half hole 12 a′ moves rightward to a location alignedwith the second half hole 12 b″, with the first half hole 12 a′ and thesecond half hole 12 b″ together forming a weaving hole 12. The firstrotating member 13 a′ and the second rotating member 13 b″ are locatedin the same weaving hole 12. Thus, an extension 3 x extends from each oftwo sides of each twine portion 3 w, as shown in FIG. 6. As an example,rightward displacement of the first rotating member 13 a′ causes thetwine portion 3 w to extend rightward to form the extension 3 x′.

With reference to FIGS. 7-9, next, the driving member 14 again drivesthe rotating assemblies 13 to rotate a plurality of full-cycle turns toproduce a second row of twine portions 3 y.

With reference to FIGS. 9-11, then, the first base 11′ and the secondbase 11″ are again moved relative to the first abutment face 111′ andthe second abutment face 111″, respectively. In an example shown in FIG.11, the first base 11′ is moved leftward to a position in which eachfirst half hole 12′ moves leftward to a location aligned with theoriginally corresponding second half hole 12″, with the first half hole12′ and the second half hole 12″ together forming a weaving hole 12. Thefirst rotating member 13 a′ and the originally corresponding secondrotating member 13 a″ are located in the same weaving hole 12. Thus, anextension 3 z extends from each of two sides of each twine portion 3 y,as shown in FIG. 10. As an example, leftward displacement of the firstrotating member 13 a′ causes the twine portion 3 y to extend leftward toform the extension 3 z′.

By repeating the steps of rotating the rotating assemblies 13 aplurality of full-cycle turns, displacing the first rotating members 13′and the second rotating members 13″ to provide misalignment, rotatingthe rotating assemblies 13 a plurality of full-cycle turns, anddisplacing the first rotating members 13′ and the second rotatingmembers 13″ to their original position, each wire 3 will extendvertically in an S-shaped route, forming a net through weaving.

However, if one of the wires 3 of the net produced from the conventionalmethod for knitting a net is broken, a large, elongated hole will begenerated, as shown in FIG. 12. Thus, the objects wrapped by the net areliable to pass through the large hole. As a result, the overallstructural strength is poor, and large holes are apt to occur.

Thus, a need exists for an improved method for knitting a net in view ofthe above reasons.

DETAILED DESCRIPTION OF THE INVENTION

A method for knitting a net according to the present invention is usedon a weaving machine identical to the weaving machine (see FIGS. 1-3)for carrying out the conventional method for knitting a net.

With reference to FIGS. 1-3, the weaving machine used in the presentinvention mainly includes a weaving unit 1. The weaving unit 1 includesa base assembly 11, a plurality of weaving holes 12, and a plurality ofrotating assemblies 13. The base assembly 11 is comprised of a firstbase 11′ and a second base 11″. The first base 11′ has a first abutmentface 111′ abutting a second abutment face 111″ of the second base 11″,allowing the first base 11′ and the second base 11″ to displace relativeto each other along the first abutment face 111′ and the second abutmentface 111″. The first base 11′ and the second base 11″ are driven by apower unit to proceed with the relative displacement.

Each weaving hole 12 is comprised of a first half hole 12′ and a secondhalf hole 12″. The first half holes 12′ are formed in the first abutmentface 111′ of the first base 11′ at regular intervals. The second halfholes 12″ are formed in the second abutment face 111″ of the second base11″ at regular intervals. Each first half hole 12′ (12 a′, 12 b′, 12 c′)is aligned with one of the second half hole 12″ (12 a″, 12 b″, 12 c″) toform a weaving hole 12.

Each rotating assembly 13 is rotatably received in one of the weavingholes 12. As an example, the rotating assemblies 13 are preferablydriven by a driving member 14 to rotate. Each rotating assembly 13includes two wire holes 131. Each rotating assembly 13 is comprised of afirst rotating member 13′ (13 a′, 13 b′, 13 c′) mounted on the firstbase 11′ and a second rotating member 13″ (13 a″, 13 b″, 13 c″) mountedon the second base 11″ and aligned with the first rotating member 13′,with the aligned first rotating member 13′ and the second rotatingmember 13″ jointly rotatable. Each first rotating member 13′ has a firstwire hole 131′, and each second rotating member 13″ has a second wirehole 131″. Wires 3, 3 a, 3 b thread through the first and second wireholes 131′ and 131″. As an example, first wires 3 a thread through thefirst wire holes 131′, and second wires 3 b thread through the secondwire holes 131″.

The weaving machine preferably includes a coiling unit 2 on a side ofthe weaving unit 1. The coiling unit 2 is driven by a power unit to coila net formed after weaving.

With reference to FIG. 13, the method for knitting a net according tothe present invention includes a wire threading step S1, a firstmisalignment step S2, a first rotation step S3, a second misalignmentstep S4, a second rotation step S5, and a repeating step S6.

With reference to FIGS. 1-3, in the wire threading step S1 of thepresent invention using the above weaving machine, a plurality of firstwires 3 a and a plurality of second wires 3 b respectively threadthrough the first rotating members 13′ and the second rotating members13″. Specifically, an end of each first wire 3 a extends through thefirst wire hole 131′ of one of the first rotating members 13′. An end ofeach second wire 3 b extends through the second wire 131″ of the one ofthe second rotating members 13″. The first wires 3 a and the secondwires 3 b are pulled to extend away from the weaving unit 1. Forexample, in this embodiment, an end of each wire 3 (3 a, 3 b) is pulledand stretched by the coiling unit 2. In an example shown in FIG. 3, therelative position between the first base 11′ and the second base 11″ isdefined as an initial state. In this state, the first rotating member 13a′, 13 b′, and 13 c′ are respectively aligned with the second rotatingmembers 13 a″, 13 b″, and 13 c″. Furthermore, the first rotating members13 a′, 13 b′, and 13 c′ are respectively located in the first half holes12 a′, 12 b′, and 12 c′. The second rotating members 13 a″, 13 b″, and13 c″ are respectively located in the second half holes 12 a″, 12 b″,and 12 c″. To assist in description hereinafter, the first wire 3 aextending through the first wire hole 131′ of the first rotating member13 a′ is defined as wire 3 a′ and is represented by a bold line in FIG.14.

With reference to FIGS. 3, 14, and 15, in the first misalignment step S2of the present invention, the first base 11′ and the second base 11″ arecontrolled to displace from the initial state to a misaligned state,causing the first wires 3 a and the second wires 3 b to respectivelyextend in a first direction and a second direction to form extensions31. Specifically, the first base 11′ and the second base 11″respectively move along the first abutment face 111′ and the secondabutment face 111″ to generate a misalignment displacement. As anexample, the first base 11′ displaces rightward, and the second base 11″displaces leftward, as shown in FIG. 15. Thus, the first rotating member13 a′ displaces rightward until it aligns with an adjacent secondrotating member 13 b″ to form a rotating assembly 13. Likewise, thefirst rotating member 13 b′ displaces rightward until it aligns with anadjacent second rotating member 13 c″ to form another rotating assembly13. The rests undergo in the same manner. Thus, since the first rotation13′ is misaligned with the second rotating member 13″ and since thewires 3 are continuously pulled by the coiling unit 2, the wires 3 willfork to form an extension 31 a extending in a rightward direction (afirst direction) and an extension 31 b extending in a leftward direction(a second direction), as shown in FIG. 16. As an example, each firstwire 3 a′ displaces rightward together with the corresponding firstrotating member 13 a′ to form a rightwards extending extension 31 a′.Each second wire 3 b displaces leftward together with the correspondingsecond rotating member 13″ to form a leftwards extending extension 31.

With reference to FIGS. 15-17, in the first rotation step S3 of thepresent invention, each rotating assembly 13 is rotated an odd number ofhalf turns, causing the first wires 3 a and the second wires 3 b tointertwine with each other to form twine portions 32. Specifically,after the first misalignment step S2, the first rotating member 13 a′and the second rotating member 13 b″ are respectively located in thefirst half hole 12 a′ and the second half hole 12 b″, as shown in FIG.15. Then, the first rotation step S3 is carried out to rotate eachrotating assembly 13 an odd number of half turns. As an example, therotating assembly 13 comprised of the first rotating member 13 a′ andthe second rotating member 13 b″ rotates 5 half turns (2.5 turns) in thecounterclockwise direction. After rotation, the positions of the firstrotating member 13 a′ and the second rotating member 13 b″ are exchangedsuch that the first rotating member 13 a′ and the second rotating member13 b″ are respectively located in aligned second half hole 12 b″ andfirst half hole 12 a′. Thus, in the misaligned state, the first rotatingmember 13′ moves from the first half hole 12′ in the first base 11′through an odd number of half turns to the second half hole 12″ in thesecond base 11″ aligned with the first half hole 12′ in the first base11′. By doing so, the extensions 31 a and 31 b generate a row of twineportions 32 and 32′, as shown in FIG. 16.

With reference to FIGS. 17-19, in the second misalignment step S4 of thepresent invention, the first base 11′ and the second base 11″ undergomisalignment displacement in the reverse direction to the initial state,causing the first wires 3 a and the second wires 3 b to respectivelyextend in the first direction and the second direction to formextensions 33 a and 33 b. Specifically, the initial state is restored bymisalignment displacement in the reverse direction (moving first base11′ leftward and moving the second base 11″ rightward). Taking FIG. 19as an example, the first rotating member 13 a′ displaces rightwardtogether with the second base 11″ such that the first rotating member 13a′ and another second rotating member 13 c″ are respectively located inaligned first half hole 12 b′ and second half hole 12 b″. Thus, thetwine portions 32 extend rightward and leftward again to form a secondlayer of twine portions 33, as shown in FIG. 18. For example, the firstwire 3 a′ again extends in the rightward direction (the first direction)after the twine portion 32′ to form the extension 33 a′. The second wire3 b again extends in the leftward direction (the second direction) afterthe twine portion 32 to form the extension 33 b.

With reference to FIGS. 19-21, in the second rotation step S5 of thepresent invention, each rotating assembly 13 is rotated an odd number ofhalf turns, causing the first wires 3 a and the second wires 3 b tointertwine with each other to form twine portions 34. Specifically,after the second misalignment step S4, the first rotating member 13 a′and the second rotating member 13 c″ are respectively located in thesecond half hole 12 b″ and the first half hole 12 b′, as shown in FIG.19. Next, the second rotation step S5 is carried out to rotate eachrotating assembly 13 an odd number of half turns. As an example, therotating assembly 13 comprised of the first rotating member 13 a′ andthe second rotating member 13 c″ rotates 5 half turns (2.5 turns) in theclockwise direction. After rotation, the positions of the first rotatingmember 13 a′ and the second rotating member 13 c″ are exchanged suchthat the first rotating member 13 a′ and the second rotating member 13c″ are respectively located in aligned first half hole 12 b′ and secondhalf hole 12 b″. Thus, in the aligned state, the first rotating member13′ moves from the second half hole 12″ in the second base 11″ throughan odd number of half turns to the first half hole 12′ in the first base11′ aligned with the second half hole 12″ in the second base 11″. Bydoing so, the extensions 33 a and 33 b generate a row of twine portions34 and 34′, as shown in FIG. 20. Furthermore, in this embodiment, therotating direction of the rotating assemblies 13 in the first rotationstep S3 can be the same as or opposite to the rotating direction of therotating assemblies 13 in the second rotation step S5. Preferably, therotating direction in the first rotation step S3 is opposite to that inthe second rotation step S5. A net having enhanced structural strengthcan be obtained by intertwining the wires 3 through rotations inopposite directions.

With reference to FIGS. 21-23, in the repeating step S6 of the presentinvention, the first misalignment step S2 is repeated until the wovennet reaches a predetermined size. Specifically, the first misalignmentstep S1 is carried out again (see FIG. 23) to obtain another layer ofextensions 35, 35 a, 35 a′, 35 b, as shown in FIG. 22. By repeating thefirst misalignment step S2 through the second rotation step S5, thefirst wire 3 a extending through the first wire holes 131′ willgradually extend leftward, obtaining a net by slant cross weaving ofwires 3 a and 3 b, as shown in FIG. 22.

With reference to FIG. 24, even a rightwards extending first wire 3 a inthe net formed by the method for knitting a net according to the presentinvention is broken, the structure of the net is still maintained byseveral leftwards extending wires 3 b, because the net is formed bycross weaving. Thus, the maximal size of the hole in the net is only twomeshes. Large holes will not occur. Thus, the overall structuralstrength of the net is increased.

In view of the foregoing, by moving the first base 11′ and the secondbase 11″ to the misaligned state, rotating each rotating assembly 13 anodd number of half turns to exchange the positions of the first rotatingmember 13′ and the second rotating member 13″ in the same weaving hole12, moving the first base 11′ and the second base 11″ back to theinitial state, rotating each rotating assembly 13 an odd number of halfturns again, etc., the first rotating member 13′ and the second rotatingmember 13″ continuously move rightward and leftward to weave the nethaving high structural strength. Thus, the present invention canactually increase the structural strength of the net.

With reference to FIG. 25, in the method for knitting a net according tothe present invention, after the wire threading step S1, the firstrotation step S3 can be carried out and then the first misalignment stepS2. Next, the second rotation step S5 is carried out and then the secondmisalignment step S4. The steps are identical to the above steps and,therefore, not redundantly described. After repeating these steps, theabove net formed by cross weaving can be obtained. Thus, the method forknitting a net according to the present invention is not limited tofirstly carry out the first misalignment step S2 or the first rotationstep S3. Only alternate proceeding of the rotation step of rotating anodd number of half turns and the misalignment step is required.

In the method for knitting a net according to the present invention,each of the first wire and the second wire moves in a predetermineddirection and is continuously cross woven with another wire. Thus, evenif a wire of the net woven by the present invention is broken, severalwires extending in the other direction can still maintain the structureof the net, because the net is formed by cross weaving such that themaximal size of the hole in the net is only two meshes. Large holes willnot occur. Thus, the present invention provides an effect of avoidinggeneration of large holes.

Furthermore, since the net formed by the method according to the presentinvention can avoid large holes, the present invention can increase theoverall structural strength of the net.
